Abstract
An electrical device includes a vibrator and a controller. When receiving an electrical signal, the vibrator vibrates a vibration target. The controller inputs a first electrical pulse to the vibrator. Pulse width of the first electrical pulse is a period of time from the input of the first electrical pulse to the vibrator until displacement of the vibration target becomes maximum. After inputting the first electrical pulse, the controller inputs a second electrical pulse to the vibrator in such a way as to offset the vibration of the vibration target.
Claims17
An electrical device comprising:
- a vibrator that, when receiving an electrical signal, vibrates a vibration target;
- and
- a controller that inputs a first electrical pulse to the vibrator,
- wherein pulse width of the first electrical pulse is a period of time from the input of the first electrical pulse to the vibrator until displacement of the vibration target becomes maximum, and
- wherein, after inputting the first electrical pulse, the controller inputs a second electrical pulse to the vibrator in such a way as to offset the vibration of the vibration target.
A method for controlling vibration, the method comprising:
- inputting a first electrical pulse to a vibrator that, when receiving an electrical signal, vibrates a vibration target;
- and
- inputting, after inputting the first electrical pulse, a second electrical pulse to the vibrator in such a way as to offset the vibration of the vibration target,
- wherein pulse width of the first electrical pulse is a period of time from the input of the first electrical pulse to the vibrator until displacement of the vibration target becomes maximum.
